| Zak Seidov: Alois, better you explain (for such laypersons as me) why this interesting sequence is not interesting to you as Editor. Thx a lot.

| David A. Corneth: to me this sequence feels artificial. It doesn't add much insight into primes, though the congruence bit is mildly interesting. Looking for these primes isn't too interesting computationally. This list of primes cannot be 'anchor points' for other searches, like maybe the sequence a(n) = prime(2^n) is.

| David A. Corneth: the facebook page merely repeats this sequence.
|
|

| Zak Seidov: David, Editor of scientific publication should never say what is not in the Seq but discuss what is in. This is the golden rule : never say what is not, discuss what is in.

| N. J. A. Sloane: What is in this sequence, you ask? Answer: nothing that is appropriate for the OEIS. Zak, please take a holiday from the OEIS for six months.
